I became a Calvinist when I got saved. I was 17 (15 years ago) at the time and was not looking for Christ, for what he had to offer, or salvation. When I came to understand my sin and my need for the Gospel- Calvinism was a no-brainer. This was underscored with the fact that the woman who led me to Christ had me reading good books and the Scriptures right away. The first book that I read as a new believer was Thomas Watson's Heaven Taken By Storm.
